I have been working on tweaking a Hammond to tiny terror build for a few days. My work hasn't been a total bust, but the break-up is "papery" similar to driving a high fi amp. schematic http://r.clear.home.insightbb.com/OTT.pdf My build uses a 5U4 rectifier and cheap poly caps virtually throughout. I believe my voltages are appropriate. I adjusted the first coupling cap to .027 because of a lack of bass response. My layout is sketchy but workable and I can't get the tone cut to work for love or money. Any tips/tricks on making this little guy more manageable are appreciated.
